Both really I’d say.
Druids are different:
Night elven druids are really involved with their kind, not that open to cooperation with others, rather have their goals and follow them strictly, though with the Circle of Cenarius they do work together with tauren druids and others. They protect nature, fiercely if need be, and still many druids, even night elven ones, work independently, following own projects, like the druids that try to make the barrens green again or those that try to make Desolace green again. They’re just mostly in the ‘parent organisation’ that is the Cenarion circle.
Shamans meanwhile band together in the Earthen Ring organisation, also follow own projects and still work together often, even with the Circle of Cenarius, and they’re mainly mediators with the elements. The elements grant them their powers, they mustn’t act against the interest of the elements or risk having their abilities stripped of them, etc.
Both are organized and act in a similar way, the different is mainly that druids protect and serve the interest of nature while shamans protect and serve the interest of the the elements. Both are fine options!
Also I seem to not have seen the problem with ‘Kriegern’, I didn’t know it had a certain connotation in english. Raindancer is wise and I appreciate their input as well :>
